In all seriousness I like it in the two normal aspects: -The obvious fanart that has taken by storm, whether it shows off the normal bromance or something more...I cannot help but like them, especially if they're done so damn good...and as long as they don't go overboard. I especially love the people who actually poke at the shipping. -And of course the actual two just playing together (Pewdie has placed in one of their Co-Ops the term 'PewdieCry' so it can relate to just that).
I was never a fan of Pewdie doing co-ops (I'm rather picky when it comes to lets players, I will admit), but when he did the first No Room in Hell with him I fucking loved it.
Don't know what it is. They're just good together, they're double the humor; and I love how it seems like they're having more fun than ever playing the game with another than they would alone.
I just think they're a good duo, whether as awesome friends in game or heavy bromancing in the fanart.
I wrote fanfics about them but I did not make them have sex like every other fic does. it had to parts and the most they did was hold hands, hug, kiss, and say they loved each other. they are cute together (using the poplular belief of what cry looks like anyway.)
